Fig.1'12 isa' viewshowing the circuit,- and Fig}; 13 is alview, of thepadcontaining the medica .ment; .Fig. l tisi a view of, the handleem- I ployed when theuelectrical source isformed from twoor more cells.- 1 M I 1 An inhaler orrespirator iii-accordance with this invention comprises acombmed mouth and nose piece 1, preferably formed of an msulating material, although the same'oan be constructed of anydesirable material, ,and

when used itis adapted to be positioned over the'mouth and'nose of the patient. The combined mouth and nose piece is cut away at.

the top, as at 2, so the same will fitina proper manner, and the edge thereof hass'ecured thereto a suitable yieldingmaterial 3, which :bears againstth'e face of the patient whenthe combined mouth and nose piece is in posie tion, sothatlno inconvenience will behad when the inhaler and respirator is used.

1 Preferably the material [Sis rubber. That end of the combined mouth and nose. piece which does not engagethe face of thepatient has; formed integral therewith a perforated plate 4,.said plate 4 beingv provided centrally with anopening 5, which is termedan inlet opening, forthe vapor and medicated air, and a surrounding the'opening 5'is aconcentricallyarranged series ofopenings 6 ,whichare termed outlet-openings? and which in conjunction with'the inlet-opening 5 enables thepatient to breathe in a satisfactory manner. When the patient is inhaling the vapor and medicated air, the openings 6are closed in a manner as hereinafter set forth, and when the patient isexhausting the air from his lungsthe openings 6 areopened.

ioo

Fitted upon, suitably secured to, forming a continuation of, and projecting from the mouth and nose piece 1 at that end to which the plate 4 is arranged is avalve-casing 7, provided with a central opening 8, and said casing is further provided with a concentricallyarranged series of outlet-openings 9, surrounding the opening 8 and in alinement with the openings 6 in the plate 4. Supported within the opening 8 is a cup-shaped member 10 which is formed with an opening 11, termed an inlet-o ening, for the vapor and medicated air an which is in alinement with the opening in the plate 4. The cu shaped member forms a seat 11 for tie inlet-valve 12, the latter being preferably formed of mica; but any other suitable material can be employed. The cup-shaped member 10 is provided at its top with a series of notches or seats 13, in which is mounted a series of radially-extending arms 14, connected together at their centers, said arms acting as a sto to limit the movement in one direc tion of t e inlet-valve 12, and also acting as a means to constitute a seat for the outlet-valve 15, said valve 15 being preferably constructed of mica; but any suitable material may be employed, and is in the form of a flat ring and surrounds the cup-shaped member 10 as well as being positioned in advance of the outletopenings 9. The arms 14 at the center thereof are provided with a forwardly-projecting lug 16, extending through the inlet-valve 12,

and which acts as a guide for said valve, and

certain of said arms 14 at the ends thereof are provided with lugs 17, which extend through the valve 15 and act as guides therefor. The movement of the valve 15 in one direction is limited by the plate 4, while the movement in the other direction is limited by the arms 14. The' plate 4 upon its outer face and surrounding the inlet-opening 5 is formed with a boss 18, which when the valve-casing 7 is in position is adapted to extend in the cup-shaped member 10, so that the casing will be properly positioned, and the valve-casing 7 is formed with a forwardly-projecting annular flange 19, which is slotted, as at 20, and which constitutes one member of a coupling device for a purpose to be hereinafter referred to.

The reference character 21 denotes a receptacle for a purpose to be hereinafterreferred to and which is formed with a rearwardly-extending flange 22, forming the other member of a coupling device. Said flange 22 is provided with the lugs 23, and said flange 22 in connection with the flange 19 is adapted to constitute a coupling device for connecting the receptacle 21 to the valve casing 7, and this connection is had through the medium of the lugs 23, engaging in the slots 20 of the flange 19 and forming a inand-slot connection between the receptac e21 and the valve-casing 7. The receptacle 21 opening 24, surrounded by the flange 22 and said rear end of the receptacle 21 is furthermore provided with a concentricallyarranged series of openings 25, which constitute air-inlet openings. ithin the receptacle 21 in front of the openings 24, is arranged a filtering medium 26, and arranged within the receptacle 21, in suitable relation withrespect to the opening 24, is a pad 27, ada )ted to contain the medicament, the position of the pad 27 being forward of the inlet-opening 11 Carried by the flange 19 is a disk 19, which is positioned at such point upon said flange 19 so as to come midway between the valve-casing 7 and the receptacle 21. The function of the disk 19 is to prevent the air that is exhaled by the patient coming into contact with the forward or removable part of the inhaler, and, furthermore, the said disk 19 when positioned in a manner as stated causes the exhaled air to pass out to the sides on the rear side of the disk and all inhaled air to be drawn through the filter from the forward side of the disk, and by such an arrangement the incoming and outgoing air are separated.

The pad 27 is provided with a resistancewire 28, which extends through the pad from. edge to edge and projects from the pad 27, and the projecting ends of said wire 23 are looped, as at 29, to permit of the mounting of the wire upon the contact-posts 30, secured. to the binding-posts 31 32, which extend through the insulated end 33 of the receptacle 21 and to the said binding-posts 31 32 the leading-in wires 34 35 are connected. The leading-in wires 34 35 are connected with a suitable source of electrical energy, and a suitable switch is interposed in the circuit, so as to break and make the circuit when occasion so requires. When the circuit is made, the resistance-wire acts to heat the pad 27,0011- sequently vaporizing the medicament, and as the airis drawn through the inlet-openings 25 it will first pass through the filter and then through the pad. Consequently the air will not only be medicated, but will also be heated somewhat as the pad is heated owing to the action of the resistance-wire. When the circuit is broken, the pad becomes cool. Therefore it will be evident that when the circuit is made and the device used that during the inhalation the patient will inhale the heated vapors and the heated medicated air, and which has been found to produce a more effectual result than if the vapors and air were cold.

By way of example and as showing one form for connecting the resistance-wire 28 to a source of electrical energy, and also as showing a means for making and breaking the circuit, and also for setting up the source of electrical energy with respect to the inhaler, so that the inhaler and the source of haler, a base 36 is provided having an"up-' wardly-extending hollow cylinder 37, which constitutes a receptacle for a battery 38, the latter resting upon the coiled spring 39 withtallic cap 41.

1 with the cap 41. The cap 41 centrally thereof is formed with an opening 42, through which extends one of the poles 43 of the battery,'the other pole being the wall of the cell, said wall being metal and in contact with the cap 41/.

a The cap 41 carries a contact-post 44, which is adapted to be engaged by the snap-piece 45,

1 carried by the leading-in wire 34.

The pole 43 of the battery is adapted to be engaged, in

V a manner as hereinafter referred to, by'one end of the leading-in wire 35. the leading-in wire which is adapted to engage with the pole 43 is connected to a shiftable circuit making and breaking member 46 which is provided with an opening 47, into which extends the pole 43. her 46 has projecting from each side thereof a short shaft 48, which extends through the sides 49 of asupporting-bail, the latter being connected to the cap 41, as the cap is pro.- vided centrally with an upwardly-extending. boss 50,which extends through and engages the wall of the opening 51, formed in the base 52 of the bail. One of the shafts 48 carries a push-button 52, and between said button I 52 and the bail is mounted a spring 53, the

function of the spring 53 being to'norrnally retain the member 46 in such position that the end of the leading-in wire 35, which is connected with said member 46, will be out of contact with the pole 43.

When the member 46 is; shifted by' the patient engaging the push-button 52, that end of theleading-in wire 35 which is connected to the member 46 will be brought into contact with the pole 43 and make the circuit. The travel of the circuit is as follows: from the pole 43,

' through the leading-in wire 35, through the resistance-wire 28, thence through the wire 34, contact-post 44, cap 41 to the wall of the battery. The sides 49 of the bail are provided with eyes 54, so that a connection can be had between the valve-casing 7 and the bail,so that the latter will support the combined mouth and nose piece 1, as well as the receptacle 21. When the patient uses the device,

he holds the same by grasping the cylinder 37 V and utilizes his thumb to shift the member 46 pads carrying the medicament.

to make the circuit. If desired, the cylinder 37 can be provided with a spring-clip 55 for' holding a receptacle containing additional When the inhaler and respirator is set up in the manner "as hereinbefore stated, a' cover 56 is provided.

That end of 1 The memand which is secured to'the base 36 through tion 57.

In case it be desired to couple more than one cell asa source of electrical energy and when the patient does not desire to hold the cells a handle 58 is provided for the supporting-bail, and extending, through the handle 58 are the circuit-wires 5960, the wire 59 terminating in'a contact-post 61, which is adapted to be engaged by the leading-in wire 35, carried by the shiftablemember 46. When the handle'58 is employed, the wire 34 is dispensed with and the wire 59, connected directly to the post 31, said wire 59 extending through'and projecting from the handle 58 in a manner as shown. The circuit is made and broken in the same manner as 'hereinbefore referred to. v I

When the device is used by a patient and during the action of inhaling, the inlet and outlet valves move in the same direction, and when exhaling they move. together in a contradirection. The outlet-valve closes the outlet-openings in the plate 4 during the .act of inhaling, but when exhaling the position of the outlet-valve is such that the SC-ld outletopenings are not closed, Consequently the patient can breathe withoutany inconvenience. During the act ofexhaling the inlet' valve closes the inlet-openings.

The pad or other means which contains the medicament is detachably mounted inthe rethe medium of the pin-and-slot'connecceptacle 21, so that when occasion requires the pad or other means can be moved and a newone replaced therefor. This is obvious, owing to the manner of connecting the receptacle 21 to the valve-casing and owing to the fact that the ends of the resistance-coil are loop-ed, so that they can be conveniently mounted upon and removed off the contact posts or points 30. It will also be evident that the inhaler can be-used as protector when a person is working in a dusty or bad temperature. 6 In this connection the com bined mouth and nose piece can be used alone, the person-using it fastening it to the face by a rubber band over the head, The filtering arran ement will take up the dust, and the air wilfenter the persons lungs clear, or if used where the air is contaminated ,certain disinfectants can be placed on the pad. Furthermore, the combined mouth and nose piece is adapted to be used on various machines where treatment is given by ozone and nebuli'zed air;
